Comparison

Peptide Plug vs Protocol

Protocol (protocolapp.health) is the closest direct rival to Peptide Plug — same buyer, same outcome promise, native iOS app with Android coming soon, and a privacy model built entirely around on-device storage. Here's an honest, feature-by-feature look at where each one is stronger.

Short version

Protocol's pitch is "no accounts, no cloud, no tracking" — everything stays on your phone. That's a real advantage if on-device-only storage matters most to you. Peptide Plug stores your data in your account instead, so it's encrypted in transit, backed up automatically, and available if you switch phones or use a browser — and it adds live cost-per-dose forecasting, which isn't in Protocol's published feature list. Protocol, in turn, has AI features (a research assistant and stack builder) and a 3D injection-site body map that Peptide Plug doesn't offer.

Questions

Is Protocol more private than Peptide Plug?

Protocol stores data locally on-device with no account required and no cloud sync on its core app, and markets this directly ("no servers to send your data to"). Peptide Plug stores data in your account in the cloud, encrypted in transit and never shared with third parties, so you can access it across devices and never lose it if your phone breaks. Both are legitimate approaches — Protocol trades cross-device access for on-device-only storage; Peptide Plug trades on-device-only storage for cross-device access and automatic backup.

Does Protocol have cost forecasting like Peptide Plug?

Not in Protocol's published feature list. Protocol's features focus on dose logging, a 3D body map for injection site rotation, PK curve visualization, and an AI research assistant and stack builder — cost-per-dose and cycle-cost forecasting are not listed among them.

Which is cheaper, Protocol or Peptide Plug?

Protocol Pro is $59.99/year (about $5/mo) for AI features and unlimited protocols, or $3.99/mo for its web/Android tier. Peptide Plug Pro is $4.99/mo or $49.99/yr (about $4.17/mo). Prices are close; which is cheaper depends on which tier and billing period you compare.
